Scalable van der Waals Photonics: High-Refractive-Index Gallium Sulfide Films with Single-Crystal Optical Properties
Aleksandr Slavich, Georgy Ermolaev, Dmitriy Grudinin +15
The integration of high-refractive-index dielectrics into scalable photonic architectures is foundational to advancing integrated circuits and augmented reality (AR) displays. Van…
Solvent-Directed Femtosecond Laser Ablation: Tuning Phase and Defect Engineering in Hybrid CdPS3/CdS Nanostructures
Andrei Ushkov, Nadezhda Belozerova, Gleb Tikhonowski +8
The limited visible-light absorption of wide-bandgap van der Waals crystals fundamentally restricts their utility in solar energy conversion. Here, we report a surfactant-free, sol…
Laser-Synthesized Amorphous PdSe Nanoparticles: A Defect-Rich Platform for High-Efficiency SERS, Photocatalysis, and Photothermal Conversion
Andrei Ushkov, Nadezhda Belozerova, Dmitriy Dyubo +16
The control of material properties at the atomic scale remains a central challenge in materials science. Transition metal dichalcogenides (TMDCs) offer remarkable electronic and op…
Contact Lens with Moiré patterns for High-Precision Eye Tracking
I. M. Fradkin, R. V. Kirtaev, M. S. Mironov +9
Eye tracking is a key technology for human-computer interaction, particularly crucial in augmented reality (AR) and virtual reality (VR) systems. We propose a novel eye-tracking ap…
Tunable Nanostructuring for van der Waals Materials
Gleb Tselikov, Anton Minnekhanov, Georgy Ermolaev +19
Van der Waals (vdW) materials are becoming increasingly popular in scientific and industrial applications because of their unique mixture of record electronic, optical, and mechani…
Anisotropic van der Waals Crystal with High Refractive Index and Transparency for UV-Visible Range Applications
Aleksandr Slavich, Georgy Ermolaev, Ilya Zavidovskiy +20
Thanks to their record high refractive index and giant optical anisotropy, van der Waals (vdW) materials have accelerated the development of nanophotonics. However, traditional hig…
